I installed only "rest_framework" but used a lot of ways and they don't work already

missing ','?

You will need that later for sitemap django sitemap will use get_absolute_url to reverse the object

INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', # Added 'social_login', 'rest_framework', "rest_framework.authtoken", "django.contrib.sites", "corsheaders", # 'allauth', # "dj_rest_auth", # "dj_rest_auth.registration", # "allauth", # "allauth.account", # "allauth.socialaccount", # "allauth.socialaccount.providers.google", ]

does pip freeze shows this module?

django-cors-headers==3.13.0

have you added Middleware?

share entire error message, use pastebin.com or something.

Error with corsheaders

but nowhere in error is mentioned?

And this error is the same for allauth and dj_rest_auth too. So I thought that it is strange

can you share your codebase?

I can even share github

Link?

Link?

Could it be problem that I have virtualenv in parent folder but start server in api?

how to read a total number of N records from multiple tables? can anyone give me a keyword pls?

imagine we have three tables: A, B, C now the question is, how do I query these three tables, so at the end, I have a total number of N (for example, 10) records together (each of these records could be from table A, B or C)

create new virtual env

I tried, only one module installed and then the same errors

did you install all the required packages after activating the new virtual env?

What do you mean? I installed Django and only restframework and each of this packages INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', # Added 'social_login', 'rest_framework', "rest_framework.authtoken", "django.contrib.sites", "corsheaders", # 'allauth', # "dj_rest_auth", # "dj_rest_auth.registration", # "allauth", # "allauth.account", # "allauth.socialaccount", # "allauth.socialaccount.providers.google", ]

I mean pip install one

Yes, by pip, pip3 but every time "no modules" error, but i see this modules in venv/Library and in pip freeze

I've built category tree with django-mptt. What is the best way to get url for a specific product in a category like cat/subcat/subsubcat/product-name? And how to register that pattern in urls.py?

Why you want to do that?

Actually you could get the product directly and get the products that are related to the specefic category hierarchies

I think you misunderstood me. I need to be able to go to links like /cat/subcat/ and view products of "subcat" category OR to go to link like /cat/subcat/product-name and view product with slug "product-name" that is in "subcat" category

for getting this to work you should use re_path in urls.py

for getting this to work you should use re_path in urls.py

But I saw solutions with regex in "path" function. Why do I need "re_path"?

path(r"^catalog/(?P<hierarchy>.+)/", views.catalog, name="catalog") And then in my view I need to split hierarchy by slash?

yes

for getting this to work you should use re_path in urls.py

I found another path converter in the docs - path. We can write this: path("catalog/<path:categories>/", ...)
